GENERAL POWER TOOL SAFETY WARNINGS
WARNING!
- Read all safety warnings and all instructions. Failure to follow the warnings
and instructions may result in electric shock, re and/or serious injury.
- Save all warnings and instructions for future reference.
- The term “power tool” in the warnings refers to your mains-operated
(corded) power tool.
.WORK AREA SAFETY
- Keep work area clean and well lit. Cluttered or dark areas invite accidents.
- Do not operate power tools in explosive atmospheres, such as in the
presence of ammable liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
- Keep children and bystanders away while operating a power
tool. Distractions can cause you to lose control.
.ELECTRICAL SAFETY
- Power tool plugs must match the outlet. Never modify the plug in any
USER MANUAL 3
way. Do not use any adapter plugs with earthed (grounded) power tools.
Unmodied plugs and matching outlets will reduce risk of electric shock.
-Avoid body contact with earthed or grounded surfaces such as pipes,
radiators, ranges and refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
- Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
- Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled cords increase the risk of
electric shock.
- When operating a power tool outdoors, use an extension cord suitable
for outdoor use. Use of a cord suitable for outdoor use reduces the risk
of electric shock.
- If operating a power tool in a damp location is unavoidable, use a
residual current device (RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
.PERSONAL SAFETY
- Stay alert, watch what you are doing and use common sense when
operating a power tool. Do not use a power tool while you are tired or under
the inuence of drugs, alcohol or medication. A moment of inattention
while operating power tools may result in serious personal injury.
- Use safety equipment. Always wear eye protection. Safety equipment
such as dust mask, non-skid safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce personal injuries.
- Avoid accidental starting. Ensure the switch is in the off position before
plugging in.
- Remove any adjusting key or wrench before turning the power tool on.
A wrench or a key left attached to a rotating part of the power tool may
result in personal injury.
- Do not overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
- Dress properly. Do not wear loose clothing or jewelry. Keep your hair,

clothing and gloves away from moving parts. Loose clothes, jewelry or long
hair can be caught in moving parts.
.POWER TOOL USE AND CARE
- Do not force the power tool. Use the correct power tool for your
application. The correct power tool will do the job better and safer at the
rate for which it was designed.
- Do not use the power tool if the switch does not turn it on and off. Any
power tool that cannot be controlled with the switch is dangerous and
must be repaired.
- Disconnect the plug from the power source before making any
adjustments, changing accessories, or storing power tools. Such
preventive safety measures reduce the risk of starting the power tool
accidentally.
- Store idle power tools out of the reach of children and do not allow
persons unfamiliar with the power tool or these instructions to operate the
power tool. Power tools are dangerous in the hands of untrained users.
- Maintain power tools. Check for misalignment or binding of moving
parts, breakage of parts and any other condition that may affect the
power tool’s operation. If damaged, have the power tool repaired before
use. Many accidents are caused by poorly maintained power tools.
- Use the power tool accessories in accordance with these instructions,
taking into account the working conditions and the work to be performed.
Use of the power tool for operations different from those intended could
result in a hazardous situation.
